Sundance® Hot Tub Jets FAQ
Why do hot tub jets need to be replaced?
Hot tub jets are wear-and-tear components that experience thousands of hours of water flow, pressure, chemical exposure, and temperature fluctuations. Over time, jets may become clogged, cracked, loose, faded, fail to rotate properly, or lose pressure.
Common signs you need replacement jets include:
- Weak water pressure
- Jets that no longer spin or rotate
- Cracked or damaged jet faces
- Missing internal components
- Difficulty adjusting the jet direction
- Water leaking around the jet assembly
Replacing worn jets restores the hydrotherapy performance your Sundance spa was designed to deliver
What do Sundance spa jets actually do?
Jets are responsible for creating the massage therapy experience in your hot tub. They combine water flow and air to target muscles, promote circulation, relieve tension, and enhance relaxation.
Sundance® Fluidix® jets are engineered to provide various massage styles including:
- Deep tissue massage
- Pressure point therapy
- Swirling vortex action
- Oscillating massage patterns
- Neck and shoulder relief
- Adjustable intensity levels
Unlike traditional spa jets, many Sundance Fluidix® jets are designed without bearings, reducing wear and increasing durability.
How do I know which Sundance jet replacement I need?
This is our most frequently asked question.
Many Sundance jets look nearly identical but are often model-year specific. The easiest way to identify the correct replacement is to gather:
- Your Sundance spa model
- Year of manufacture
- Jet face diameter measurement
- Photo of the front of the jet
- Photo of the back of the jet (if available)
If you're unsure, simply send us a few photos of your spa and the jet you need to replace. Our team can help identify the correct Sundance Genuine Part before you order.
Don't guess. Ordering the wrong jet can lead to fitment issues and unnecessary returns.
Can I replace a Sundance spa jet myself?
In most cases, yes.
Many Sundance jet inserts are designed to be removed and replaced from inside the spa without specialized tools.
Typical replacement steps:
- Turn off power to the spa.
- Remove the old jet by twisting and pulling according to your model.
- Inspect the jet body for damage or debris.
- Align the new jet.
- Twist into place until it locks.
- Restore power and test operation.
Most homeowners can replace a jet in just a few minutes.
Should I buy genuine Sundance replacement jets or aftermarket parts?
We strongly recommend Genuine Sundance® replacement jets whenever possible.
Benefits include:
- Exact fit and compatibility
- Factory-original hydrotherapy performance
- Correct water flow characteristics
- Matching color and finish
- Improved durability
- Warranty protection
While some aftermarket jets may appear similar, even small differences can affect performance, water pressure, fit, and longevity. Genuine Sundance parts help ensure your spa continues to operate as designed.
What if water is leaking around a jet?
A leaking jet should be addressed promptly.
Common causes include:
- Worn gaskets
- Loose retaining rings
- Cracked jet bodies
- Aging seals
- Plumbing connection issues
Ignoring a jet leak can lead to:
- Water damage inside the cabinet
- Mold or moisture buildup
- Reduced energy efficiency
- Potential damage to pumps and plumbing components
If you notice water loss or moisture near a jet, contact us for troubleshooting assistance. We can help determine whether you need a jet insert, gasket, or complete jet body replacement.
Why does my jet have weak pressure or stop rotating?
A jet that isn't performing properly doesn't always need replacement, but it often indicates wear or blockage.
Common causes include:
- Mineral buildup
- Debris obstruction
- Internal wear
- Broken rotating components
- Aging jet inserts
If cleaning the jet doesn't restore performance, replacing the jet insert is typically the fastest and most cost-effective solution. Many owners are surprised how dramatically a new genuine Sundance jet can improve water flow and massage quality.
I don't know which jet I need. Can you help?
Absolutely.
Because Sundance has used many jet styles across different series and model years, identifying the correct replacement can sometimes be challenging.
To make things easy:
✅ Send us your spa model and year
✅ Email us photos of the jet
✅ Include a measurement of the jet face if possible
Our experienced parts team will help identify the correct Genuine Sundance Replacement Jet and ensure you receive the right part the first time.
